For once I agree with Paul Graham. I expect his post to be surprisingly unpopular with this crowd, as it sleights a core tenet of our postmodern age. Namely, he's arguing for a form of objective truth and of "the good". A statistical derivation of this good for sure (and qualitative as opposed to a Benthamist, quantitative utilitarianism), but a good nonetheless. But I applaud PG for taking this stance. Truth is not…
While you claim to oppose the postmodern idea that there is no truth, you’ve ceded the premise to the postmodernists by framing truth in their terms of objectivity and subjectivity. The success of the postmodernists was precisely to discredit all “subjective” truths by way of distinguishing them from “objective” truths, which no common person can deny. A stronger position is one that does not require the truth to be…
I do not. What I am saying is that knowledge—if such a thing exists at all and is worthy of defense by humans—can be addressed in a rational, objective way.
Lots of things are approximations, but we do not deny the existence of categories as useful phenomena or an epistemological tool. To paraphrase a famous exchange of ideas, GB Shaw: "All chairs are quite different" vs. Chesterton: "Well how do you then call them all chairs?"
The postmodernist sleight of hand is to say that perhaps because there are differing contexts that there is not a universal tendency; such a commonality is either non-existent or should be disregarded. They would not categorically discard visceral human experiences that lead to say "thirst" or "hunger" or "anger", but they will claim that there are not common phenomena that engender "awe" or "wonder" or "intrigue". I disagree with that statement. That humans can reliably classify things that are "beautiful" across cultures (and have done so for millenia, even when they hate each others' cultures), shows there is a common tendency towards taste.
When thirsty, many people drink water, but the postmodernist looks at the few drinking Brawndo and has to deny the generalization that water quenches thirst but of thirst entirely.
